Hitler's Reign of Terror is an independently released 1934 Pre-Code social problem film that attacked Adolf Hitler. The film is a combination of live action and documentary. Despite the fact that the New York state censor board refused the film a license, it played for two weeks in New York City in theaters filled to capacity. In Chicago the film was only released after the title was changed to Hitler Reigns to placate the German government. Mordaunt Hall gave the film a negative review in The New York Times when it was released. Film Daily scoffed at the film for its prediction that Hitler's Germany was a future threat to world peace.
